Car owners that want to have a unique car, stand out against the other, clearly and logically. You can do an external tuning, but it will change only the appearance of the car, but in no way will affect the characteristics of the car, except that worsen them. For example, the ' installation of the wing failure may affect the aerodynamic parameters of the car. But, if you want to "disperse" car, that is, make it more powerful, it will have to go a more complicated way than airbrushing, trim and install the Dodger.

One way of forcing car is tuning the exhaust system. What it is? First you need to understand how to operate the exhaust system, what does it work and what you can change in this system. In a normal car exhaust system allows you to place the exhaust gases generated in the combustion chamber of the engine, and at the same time by the sound of the exhaust.
After the outlet valve is opened, the products of combustion with almost supersonic speed rush to the outlet pipe. And in the cylinder and the exhaust pipe when the speedy deletion of half of the combustion products formed a period of low blood pressure. Automotive specialists investigated whether the length of the exhaust pipe on the purification efficiency of the cylinder. It turned out that is not, but here is the length of time depends on dilution: with increasing lengths of pipe, within certain limits, this period also increased. Moreover, each engine operation mode has its optimum length of the exhaust pipe.
While the internal combustion engine in the exhaust system are two processes. The first is the movement of gas through the pipes, the fluctuation of varying degrees of dempfiruetsâ. The second is the spread of sound (shock waves) in Gaza. Both of these processes affect the degree of filling of the cylinders. The smaller the resistance to flow, that is, the greater the diameter of the pipe and the shorter, the better quality and less power loss to purge. But this does not mean that you can to shorten the pipe and increasing its diameter. For normal (not sports car) the diameter of the exhaust pipe more than 45 mm at length of 3 meters to reduce dynamic resistance are not affected.
To improve purge cylinder and, consequently, increase the torque of the engine exhaust system, you can install the reflector (resonator), which is mounted at a distance from the valve. This operation is called "tuned exhaust ', it serves to adjust the torque curve. If you want to raise the engine up to sports figures, the resonator is tuned to plot a curve of real-time graphics, falling after the maximum value. To improve thrust at low revs resonator is tuned to a growing portion of the maximum.
By reworking the exhaust system you can increase the power of the engine at 10-15 HP But to get that kind of "allowance", to change practically all components of the exhaust system: the resonator, the catalyst, "pants", Bank 75. To the silencer does not affect the resonant properties, it must be installed further away, it just turn off the sound by multiple reflection in the maze. In sports the same machines in this way, you can get more power and more, but only because for these machines are not so significant volume of exhaust, with officially approved 100 DB, they may have and 120 DB.
